The vibration is still going to kill you, though. You don't get pinpoint stars like that in a 30 sec exposure on a tripod on a vibrating surface. Unless it's doing active image correction, I find it implausible.
1. Have you ever been on a commercial airliner? There's not really much vibration. (Yes, there's vibration, but the amplitude is not more than like a millimeter.)
2. Mechanical image stabilization exists and is common. Not sure whether fisheye lenses have it, but:
3. Fisheye lenses GREATLY reduce parallax error. Do the math out.
4. The vibration would NEED to be rotational, not lateral, for all the same reasons discussed above (stars are too far for lateral motion to change their apparent position). However little lateral vibration there is in an airplane, I guarantee there's even less rotational vibration. Sound/vibration simply doesn't work that way.
